It is installed on the laptop, although i have just been using Firefox to connect to the internet. Do you think it would be a problem with having IE8 on the laptop?
I've managed to set the MTU of the router to 1500 and it now stays the same on the setup screen. But this has still not fixed the problem, no pages will load up.
I tried to set the MTU to 1500 but everytime i did and went back into the setup, it had reverted back to 1492. Alas, I still am unable to wirelessly connect to the internet.
